1968-1972 Chevrolet Chevelle Long Tube Headers Hooker Super Competition exhaust-system Muffler Inlet Diameter: 3Overview With Hooker Super Competition the objective has always been to make the maximum horsepower and to put it at the optimum point in the power curve. It takes a lot of time and money to do the job right. We will sometimes spend up to 2 to 3 times more just to make the Super Competition header work only 5 to 10% better. That commitment to excellence has made Hooker Headers the winningest header manufacturer in automotive drag racing history.
